1 Application filed January16,1899. Serial No. 702,255. (ModeL) T0 at whom it may concern: 7

Be it known that I, EDWIN J. YOUNG, a citizen of the United States, residing at fadsworth, in the county of Medina and State of Ohio, have invented a certain new and useful Improvement in Injectors, of which the following is a full,clear,and exact description.

.This invention relates more especially to that class of injectors which are used on 10- comotives; and the object of the invention is to provide for the delivery of the water to the boiler when quite'warm or hot and also to enable the engineer constantly to observe the operation of the injector at the overflow.

In carrying out my invention I use a main overflow-valve located just over the overflow-nozzle and operated positively by connection with the 'steam-valve-actuating devices, so that the said main overflow-valve is always open in starting or stopping the injector and when the steam is shut oft from the injector andis closed gradually as the steam is admitted to the injector, the said valve serving also to exhaust the steam for raising the water. This mainoverflow-valve in not wholly closed until the jet is established, and when it is closed the steam-valve is wide open. In connection with this main overflow-valve I use anauxiliary or secondary overflow-valve, which is openedwhen the injector is at work in order to enable the engineer to observe the spilling at the overflow,

andthus have visible evidence of the operation of the'injector. WVhen extremely warm water is used, both the main and the 3/l1Xll". iary overflow-valves are closed, so as to pre-.

' vent the injector from spilling at the over- Having thus stated the principle of my invention, I will proceed now to set forth the best'mode in which I have contemplated applying that principle, and then will particularly point outand distinctlyclaim the part,

5o' tor constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section of same. Fig. 3 is a vertical transverse section taken substantially in the plane of the center of the overflow. tial end view'taken substantially inthe plane immediately to the right, Fig. 2, of the watervalve handle. Fig. 5 shows the details of construction of the water-valve-operating device. l The casing a may be of approved form and provided with the steam-inlet b, the waterinlet 0, the overflow d and its passage (1, and the boiler-tube e. l

f is a socket to receive the bolt by which the injector is applied to a locomotive.

The steam-valve g g, reducingnozzle 1 steam-jet g ,'lit'ting-tube g combining-tubes q 9 delivery-tube g and check-valve g all arranged in alinement within the casing a, may be of any approved construction. As herein shown, they are substantially similar in construction and operation to equivalent parts in my Patent No. 495,286, dated April 11, 1893, and as in that patent, so here, the steam-valve has the valve-rod i,

which is connected by a yoke i with the hand lever t the latter being pivoted upon the easing and having a vibratory motion thereon which is converted into a rectilinear reciprocating motion of the valve-stem.

The steam-valve is arranged in a cylinder a, which is made as a screw-cap titted in the end of the casing a and provided with a stuffing-box and gland a for, the valve-rod 2'.

j is the main overflow-valve, which is substantiallya piston arranged in a segmental chamber j, which is located crosswise of the overflow-passage d and has the'transverse valveseatj interposed between the overflowchamberand the overflow, and this chamber 3' is accessible through a screw-cap j The valve j is provided with a valve-stem Z, which passesthrough a tube or sleeve 'm. Thetube or sleeve m is supported in the wall in of the casing a and extends thence out beyond said wall and forms an inclosing bearing for'said stem. Surrounding this sleeve m is a shell 71-, the inner end of which is enlarged and perforated, as shown at n, to form the waterpassage-controlling valve. This enlargement Fig. 4. is a par-- at, which forms the water-valve, is properly seated to rotate in the water-tube c to permit the passage of the water into the injector and to cut off the supply. Said valve is removably seated in the casing by a stuffing-box n tapped into the said casing and suppliedwith the gland n inorder to make a tight joint. The outer end of the shell 11 extends beyond the sleeve m and is supplied with a suitable gland or stuffing-box 0.

The stem Z is connected by a yoke Z with the steam-valve rod 2' and derives reciprocating motion therefrom. The sleeve m, which forms-a bearing for the valve rod or stem Z, while permitting the free reciprocation of the said stem, is made steam-tight by terminating within the packed end of the shell 77..

In order to operate the water-valve, its shell 12 isslabbed off, as shown at' of, Fig. 4c, and such slabbed-off portion is provided with the ring p, Figs. 4 and 5, having its internal bore Y complemental to the external contour of the slabbed-off portion of the shell '11, so as to turn with said shell. This ring p is provided with a lug p to coiiperate with the handle presently described, and it also has the stoplugs 132 19 which come in contact with the casing to limit the movement of the watervalve. q is a handle having the'ring end g, which encircles the projecting end of the shell 77. next adjacent the ring 10, and the ring end .61 has a number of grooves g with either one of which the lug p of the ring 19 is engaged in order to set the handle q normally to the right or left hand or midway, according to the locationof the injector and the engineers preference. The gland or stuffing-box 0 may serve as the medium, with or without the nut 0, for holding the handle q in operative connection with the ring 19, and when therhandle and ring are connected as described then by vibration of the handle the water-valve may be rotated and more or less opened or closed,

as may be desired.

The ringp may be provided with a scale 4" to cooperate with indexes r on the casing, as in Fig. 4c, in order to indicate the position of the water-valve.

The auxiliary overflow-valve 8 may be of the ordinary check-valve construction; butI prefer to supply it with the adjustable stem s, which may be screwed down tight, so as to prevent the opening of the check-valve s, and consequently theautomatic operation of said valve, this being a desirable feature with some engineers and in some circumstances.

It will be observed that the steam-inlet Z) is divided from the water-chamber by-the wall t, and that the water-inlet tube and the waterchamber are separated by the valve 42, and that the water-chamber and the overflowchamber are separated by the wall m, and

' that the overflow-chamber and the overflownozzle are separated by. the valve-seat j and valve 9'.

It will be seen that the combining-tubes are erected in or form part of the skeleton. or

open-work or perforated frame 9 so that the spilled water may escape into the overflowchamber.

In ordinary injectors where the overflow is 'open the water becoming warm expands and .my machine will-work as an open-overflow machine and will show the spill at the nozzle or-exhaust, and thus the engineer may know when the jet is broken. As this auxiliary overflow-valve is quite small, much less water willv spill when the jet is brokenthan is the case with the ordinary injector. This auxiliary overflow-valve may be closed and retained closed so as to cause the machine to exhaust, as it will, freely through the main overflow-valve. This main overflow-valve j is always open in starting or stopping the inj ector and when the steam is shut off from the injector and is closed gradually as the steam is let into the injector, and as the injector exhausts through this valve the said valve practically controls the raising or lifting of the water. This valve is not wholly closed until the jet is fully established, and it is not closed until the steam-valve is wide open.

In starting the injector the auxiliary valve 5 is not necessarily used, as the main valve j has sufficient exhaust to start the injector. The auxiliary valve is only used as such when it is desired to watch the operation of the injector by means of spillingat the overflow.

It is possible to work the injector with the .water, both of the valves j ands must be closed to prevent spilling through the overflow.

I do not limit my invention to the mere details of construction and wish to beunderstood as so claiming my said invention.

What I claim is- 1. Aninjector,havingasteam-valve,amain overflow-valve, a water-chamber,an overflowchamber, and a tube or sleeve mwhich separates the said water-chamber from the overflow-chamber, the overflow-Valve rod extending through said tube or sleeveand connected with the steam-valve-operating mechanism, substantially as described.

2. An injec'tor,having a steam-valve,a main overflow-valve which controls communication between the combining-chamber and the overflow-chamber, connections between the two Valves, and a tube or sleeve separating the Water-chamber from the overflow-chamber and through which the said overflow-valve rod passes, substantially as described.

3. In an injector, an overflow-valve having a stem extending longitudinally through its casing, a tubular bearing for said stein, a tubular Water-valve surrounding the said bearing, and means to rotate the said Water-valve around said bearing to open and close the Waterway, substantially as described.

4:. In an injector, an overflow-valve movable longitudinally of the machine, a longitudinal bearing for its stem, a Water-valve made as a tube and surrounding said bearing, the outer end of the said tube provided with a handle for operating the same and capable of adjustment for use on the right-hand or the left-hand side or at intermediate points, substantially as described.

5. An injector, comprising a steain-valve, a main overflow-valve, connections between them by which they are operated simultaneously, and an auxiliary overflow-valve of relatively small size and adapted to be operated independently of the main valve and the steam-valve, substantially as described.

6. In an injector, the combination with a reciprocating longitudinally arranged overflow-valve, and a bearing-sleeve thereforar ranged transversely of the Waterway, of a Water-valve made as a tube and supported upon the said bearingsleeve and projecting outwardly of the casing, and means to operate it, substantially as described.
